Not sure the US was slow on this. Trump banned all Chinese from entering the country in late January. That was early in the outbreak. He was called a racist, xenophobe and a hater. It was already too late since the Chinese had been hiding the outbreak since November. That's criminal if we had any kind of world court they would be held responsible for trillions of dollars of damages. They locked away any medical provider that had the temerity to actually speak up about what was happening. That would have been early enough to stop the outbreak but it made the regime look bad.

China has a lot to answer for and should be made to pay for their cover up.
